Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of optical cable production and manufacturing, and particularly relates to an optical cable oil paste high-speed automatic coating device and a coating method. BACKGROUND

[0002] Water resistance of an optical cable refers to a series of measures taken to prevent water from entering the interior of the optical cable, which is crucial to the performance and service life of the optical cable. Water entering the interior of the optical cable can cause an increase in fiber attenuation, affecting the transmission quality of signals. When water enters the interior of the optical cable, the water will interact with the glass material in the optical fiber, causing micro-bending loss, so that the light signal is scattered and absorbed during transmission, reducing the signal strength; and long-term water erosion of the optical cable can also damage the metal components in the optical cable, such as the reinforcing core and the armor layer, thereby causing the mechanical properties of the optical cable to decrease, and even causing the optical cable to break. Therefore, water resistance of the optical cable is particularly important for the production and use of the optical cable.

[0003] The existing water resistance methods of the optical cable mainly include dry water resistance and oil paste water resistance. The dry water resistance mainly adopts the forms of water resistance powder, water resistance yarn or water resistance tape, and water resistance is achieved by adding water resistance structures in the interior of the optical cable; the oil paste water resistance mainly coats water resistance paste in the interior of the optical cable, the water resistance paste fills the gap in the interior of the optical cable, and when external water enters, the water resistance paste will absorb water and expand to block the interface of the optical cable where the water resistance paste is located, so as to avoid the external water from continuing to enter the interior of the optical cable, thereby achieving good water resistance effect.

[0004] The water resistance paste mainly adopts cable core oil paste filling and metal belt surface spraying oil paste, and the metal belt spraying oil paste mainly adopts an electromagnetic valve spraying device to control the spraying length and spacing of the oil paste. With the gradual increase of the production rate of the optical cable, the spraying rate of the electromagnetic valve spraying device also needs to be gradually increased. When the production rate continuously increases, the opening and closing frequency of the electromagnetic valve reaches the upper limit, causing the spraying device to frequently have problems such as oil paste blockage and valve wear, which affects the production quality of the optical cable, and makes it difficult to increase the production efficiency of the optical cable.

[0067] Further, the calculation of the longitudinal wrapping length of the steel belt 16 in the present application specifically includes:

[0068] Obtaining initial positions A(x1, y1) and B(x2, y2) of both ends of the steel belt 16 and a center axis position O(x3, y3) of the cable core 15, setting that the both ends of the steel belt 16 are located at the same horizontal height, so y1=y2, the length of the steel belt 16 is x2-x1, the outer peripheral size of the cable core 15 after wrapping the steel belt 16 is 2π(y3-y1), and the overlap length of the steel belt 16 is (x2-x1)-2π(y3-y1), setting the oil paste coating thickness as d, and the single oil paste coating amount is ((x2-x1)-2π(y3-y1))*d.

[0072] When the oil paste spraying amount of the nozzle 17 reaches the set spraying amount, the spraying work is continued; when the oil paste coating amount of the nozzle 17 cannot be adjusted to the set spraying amount, it is determined that the nozzle 17 is blocked, the position of the piston 18 is adjusted, the piston 18 closes the opening of the nozzle 17 of the first spraying mechanism, the control assembly switches to work the second spraying mechanism, and the second spraying mechanism continues the spraying work.

[0073] It is worth noting that the interval between the first spraying mechanism and the second spraying mechanism in the present application is equal to the interval between the grease spraying points on the cable core 15, so that after the first spraying mechanism is blocked, the grease sprayed by the second spraying mechanism continues to fall on the last spraying point of the cable core 15 to compensate for the first spraying mechanism, realize continuous production spraying of the grease, and ensure the continuous and stable production of the optical cable.

[0074] Those skilled in the art will easily understand that the above description is only the preferred embodiment of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
